| W-band ESR(EPR) measurement system (liq.-helium-free type) |
| esr01002021207-11 |
| This system is a highly sensitive W-band ESR spectrometer. It is a liquid-helium-free type, and the injection and transfer of liquid helium is not required. We adopt a dielectric waveguide for the guide of millimeter-wave which employs a new concept similar to optical fiber techniques. The feature of this system is as follows. ･ Liquid helium is not required for coolant of superconducting magnet. ･ We decreased the propagation loss of the millimeter wave to 1/3 of the metallic waveguide, and succeeded to make high sensitivity of the measurement. ･ We succeeded to make the structure that is separable a reflection wave of the Fabry-Perot resonator from an incident wave. Thus high sensitivity of the spectrometer was achieved. ･ We made the millimeter wave waveguide more thin, and Fabry-Perot resonator smaller. The diversification of the system pertinent to the analytical purposes was realized. ･ The Fabry-Perot resonator is open-air type. Then large sample can be applicable. ･ The operation is easy, and it is highly sensitive. ･ It is suitable for the ESR measurement of the magnetic substances, dielectric substances, piezoelectric elements, and biological radicals. |
| Standard X-band ESR(EPR) measurement system |
| esr02002021207-12 |
| This system is a highly sensitive X-band ESR measurement system. Organic free radical can be easily measured. It is possible to use widely as an analysis and evaluation system in the fields of biochemistry and environmental science. |
| Desk-top type ESR(EPR) measurement system |
| esr04002060505-02 |
| It is very compact desk-top type ESR measurement system, and it is easy to use on the site, as required. It has higher sensitivity than standard type X-band ESR measurement system. It is a small model of 27kg in weight by using the rare earths magnet. You can install the automatic liquid transportation unit by an optional requirement. It can perform the mixture measurement of the water-solution sample and analyze by PC control. It can be used for the process monitoring, for ESR sensor, and for remote control unit, etc. * Single purpose specification - It is designed to settle the magnetic field and the frequency according to the purpose. |
| Alanine dosimetry ESR(EPR) equipment |
| esr31 |
| It is the single purpose specifications portable ESR( electron spin resonance) device which KEYCOM Co., Ltd. developed. It is a type for alanine dosimetry. It specialized a measurement object in an alanine origin radical. It conforms to JIS standard (JIS Z4571). It is the device which is more compact for high sensitivity than the general-purpose ESR device by setting microwave frequency in 9.8GHz, 350 resonance magnetic field mT. In addition, I realized thorough PC control and succeeded in what I used the Mn2+ signal which became inside standard and adopted for revision of magnetic field strength and the absorption strength. |
| ESR(EPR) measurement system for magnetic property |
| esr05002061101-07 |
| This system is for the magnetic materials, especially the best for the research such as Spintoronics and Quantum dots technology. ･ It has the measurement sensitivity more than that of standard type X band ESR system, because it uses ferromagnetic resonance(FMR) . ･ You can rotate the specimen by two axis accurately, and can incline the specimen. ･ You can change the static magnetic field from zero to high magnetic field up to 500 mT. |
